* Link: http://www.bin-co.com/php/scripts/xml2array/
|
|
* Portions significantly re-written by mike@macgirvin.com for Friendica (namespaces, lowercase tags, get_attribute default changed, more...)
|
|
* Arguments : $contents - The XML text
|
|
* $namespaces - true or false include namespace information in the returned array as array elements.
|
|
* $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value.
|
|
* $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance.
|
|
* Return: The parsed XML in an array form. Use print_r() to see the resulting array structure.
|
|
* Examples: $array = xml2array(file_get_contents('feed.xml'));
|
|
* $array = xml2array(file_get_contents('feed.xml', true, 1, 'attribute'));

"This means: $length should not be even,

by 4 6-bit-chars. These 4 chars must not be

split between two encoded words, according
